Abstract

A detector base for fixing to a mounting surface may include a connection for connecting to a detector line of a hazard alarm system and a first connection side for releasably attaching a hazard detector embodied as a point detector. The first connection side may be electrically and structurally co-ordinated with a second connection side of such a hazard detector, such that the latter is releasably attachable to the detector base and is indirectly connectable via the latter to the detector line. The detector base may include a radio device affixed to the detector base and serving for transmitting position data of the detector base mounting location and/or for transmitting a reference to a database having said position data. The radio device may be based on a Bluetooth low energy standard.

Claims

1. A detector base for fastening to a mounting surface, the detector base comprising:

an electrical connection for connecting the detector base to a detector line of a hazard alarm system;

a first connection side for releasably attaching a hazard detector embodied as a point detector,

wherein the first connection side is electrically and structurally matched to a second connection side of the hazard detector for releasable attachment of the hazard detector to the detector base and thereby indirect connection of the hazard detector to the detector line, and

a radio device affixed in the detector base and configured to transmit at least one of position data of a mounting location of the detector base or a reference to a database with position data of the mounting location of the detector base.

2. The detector base of claim 1, further comprising an optical and/or acoustic alarm unit that is triggered via the detector line and a signal or data link.

3. The detector base of claim 1, wherein the detector base is configured to supply electrical energy to the radio device via the detector line.

4. The detector base of claim 3, comprising an energy store configured to buffer the electrical power supply of the radio device.

5. The detector base of claim 1, wherein the radio device is a Bluetooth radio device based on a Bluetooth low energy standard.

6. The detector base of claim 1, wherein the detector base is configured to detect a signaling of a fire alarm on the detector line and to activate the radio device with a higher mean transmission power.

7. The detector base of claim 6, wherein the radio device is activatable with a maximum transmission power of 10 mW, 25 mW, 50 mW or 100 mW.

8. The detector base of claim 1, comprising a circuit carrier with a large-surface ground plane as a radio-based part of the radio device,

wherein the radio device has radio electronics arranged on the circuit carrier and a ring-shaped antenna arranged at a distance from the ground plane, and

wherein when the detector base is attached to the mounting surface, the antenna is further away from the mounting surface than the ground plane of the circuit carrier.

9. The detector base of claim 1, wherein when the hazard detector is attached to the detector base, the detector base has a larger outside diameter than the attached hazard detector, and

wherein the radio device has at least one antenna arranged in the detector base and lying radially further outside compared with the accommodated hazard detector.

10. The detector base of claim 9, wherein the antenna is ring-shaped.

11. The detector base of claim 10, comprising a circuit carrier with a large-surface ground plane as a radio-based part of the radio device,

wherein the radio device has radio electronics arranged on the circuit carrier,

wherein the ring-shaped antenna is arranged at a distance from the ground plane, and

wherein when the detector base is attached to the mounting surface, the antenna is further away from the mounting surface than the ground plane of the circuit carrier.

12. The detector base of claim 8, wherein the ring-shaped antenna is a PIF antenna.

13. The detector base of claim 1, comprising a control unit connected to the radio device via at least one of a signal link or a data link,

wherein at least one of the position data, a reference to a database with this position data, an identifier specific to the detector, or a web address is/are stored in the control unit, and

wherein the control unit is configured to forward the stored data for outputting via radio to the radio device.

14. The detector base of claim 1, comprising a control unit connected to the radio device via at least one of a signal link or a data link,

wherein the control unit is configured to:

check a validity of at least one of position data received via the radio device, a received reference to a database with the position data, or a received web address, and

if the data is determined to be valid, store the data in the control unit or in the storage device connected to the control unit.
